Verdict

The call

The clearest difference is price: Geotag Alpha at Free against Lumy's $7.99. Geotag Alpha also leads on review sentiment (89% vs 79%). Lumy's advantage is update cadence (every 3 days vs every 5 weeks) and ratings volume (2.5K vs 26). On rating, ads, in-app purchases and monetization model there is nothing between them.
